DefenceTalkEspoo, Finland: Unmanned aerial vehicles (UAV), commonly known as drones, are widely used in mapping, aerial photography, rescue operations, shipping, law enforcement, agriculture, among other things. Despite great potential for improving public safety, use of drones can also lead to very undesirable situations, such as privacy and safety violations, or property damage. There is also […]https://www.defencetalk.com/new-research-improves-drone-detection-74865/

Most nuclear data measurements are performed at accelerators large enough to occupy a geologic formation a kilometer wide, like the Los Alamos Neutron Science Center located on a mesa in the desert. But a portable device that can reveal the composition of materials quickly on-site would greatly benefit cases such as in archaeology and nuclear […]

TRX receives the first prototyping contract from the Army RCCTO’s inaugural Innovation Day, a program supporting new rapid prototyping efforts and designed to accelerate the transition of emerging technology to soldiers. TRX Systems, developer of NEON® GPS-denied location technology, has been selected by the U.S. Army to deliver a prototype tactical electronic warfare kit for […]

DefenceTalkResearchers have demonstrated proof of concept for a novel low-energy nuclear reaction imaging technique designed to detect the presence of “special nuclear materials” – weapons-grade uranium and plutonium – in cargo containers arriving at U.S. ports. The method relies on a combination of neutrons and high-energy photons to detect shielded radioactive materials inside the containers. […]https://www.defencetalk.com/new-technique-could-improve-detection-of-concealed-nuclear-materials-67306/

DefenceTalkSquid are the ultimate camouflage artists, blending almost flawlessly with their backgrounds so that unsuspecting prey can’t detect them. Using a protein that’s key to this process, scientists have designed “invisibility stickers” that could one day help soldiers disguise themselves, even when sought by enemies with tough-to-fool infrared cameras. The researchers will present their work […]https://www.defencetalk.com/squid-inspired-invisibility-stickers-could-help-soldiers-evade-detection-63655/

DefenceTalkResearchers are refining for Army use a commercial technology that will allow Soldiers to accurately and rapidly detect an array of chemical and biological hazards – from mustard agent to anthrax – and then transmit those results to their higher command. At the same time, the technology is smart enough to differentiate between those chemicals […]https://www.defencetalk.com/new-devices-may-soon-help-soldiers-detect-chemicals-bio-threats-63196/

DefenceTalkIn today’s world, in which the threat of terrorism looms, there is an urgent need for fast, reliable tools to detect the release of deadly chemical warfare agents (CWAs). In the journal ACS Macro Letters, scientists are reporting new progress toward thin-film materials that could rapidly change colors in the presence of CWAs — an […]https://www.defencetalk.com/detecting-chemical-weapons-with-a-color-changing-film-62311/

DefenceTalkExtraordinarily Thin Thermal Barrier Gives Automatic Weapons Nearly Impenetrable Cloak to Hide Hot Barrels, Gas Tubes, and Sound Suppressors Concept Group, Inc. has disclosed that the company is developing the new Insulon® Thermal Cloak™ heat barrier for use on automatic weapons. The barrier, which is attached to the fore-end of the weapon, uses a hair-thin […]https://www.defencetalk.com/thermal-cloak-prevents-weapon-detection-by-thermal-imagers-62182/

DefenceTalkNASA’s research in unmanned aerial systems (UAS) may soon provide a means for early detection and mitigation of fires in the Great Dismal Swamp National Wildlife Refuge, a nearly 50,000-square-acre region centered on the Virginia-North Carolina border. NASA’s Langley Research Center, in nearby Hampton, Virginia, has signed a one-year agreement with the Department of the […]https://www.defencetalk.com/nasa-aeronautics-research-tests-new-tool-for-early-wildfire-detection-60728/

DefenceTalkSecurity forces worldwide rely on sophisticated equipment, trained personnel, and detection dogs to safeguard airports and other public areas against terrorist attacks. A revolutionary new electronic chip with nano-sized chemical sensors is about to make their job much easier. The groundbreaking nanotechnology-inspired sensor, devised by Prof. Fernando Patolsky of Tel Aviv University’s School of Chemistry […]https://www.defencetalk.com/nano-sized-chip-sniffs-out-explosives-far-better-than-trained-dogs-60259/
